#types of variables in java

[mypatrolobservation]

Java Variable Types

Java is a statically-typed language, which means that variables have to be declared before they can be used. Java is also a strongly typed language because all the data types are already defined in it. variable is a container that stores a value. Before using a variable, it has to be given some value. The value stored in a variable can be changed during the execution of the program. Every variable in Java has a specific type, which determines the size and layout of the variable's memory.

I tried to make something since Animation vs Coding came out. (I don't care about misspelling.)

This is a joke with no punch line because, while it is certainly in-character to these 2 terrorists, it is not a joke I am committed to make. I hope you don't even know what codes they are reacting to.

So, now the punchline is... Everything is so bad from the ground-up, The Dark Lord doesn't know where to start? And The Chosen One somehow ended up insulting ONE normal thing, enraging TDL? Good enough.

I thought about deleting the entire thing, but it was such a perfect way to showcase that me, the author, can "play" a character who much more knowledgeable than I am, because I don't code.

(I don't code beyond getting a bad grade in basic Java and superficially studied C, C++ and C# just to make my resume more attractive. I got my job, I don't care.)

I didn't even know what is an "Enum" before making this comic. Do your research and cherry-pick correct information, and you can fool the average audiences before an actual expert shows up.

One quirk I gave to TCO and TDL (most likely the rest of digital creatures), is that they influenced by the code they speak out loud. TCO has randomized capital letter throughout their speech, but say "Floor" the exact way it appears in code, twice, because string data is case-sensitive. They have free will and can choose not to execute friend certain scripts or simply refuses to say it out loud.

After this, TDL is putting TCO in CODE dot ORG jail. A very great place to start learning, by the way. (Unlike Brilliant, it's free.)

I am explaining things under the cut

You watched AvC, so you already know what is constant and variable... but still;

Gravitational acceleration is a constant.

Speed is a variable.

In your program, you would want some value to change, some to stay the same.

Enum is a type of class.

Class is a collection of data that can either be variables or constant, they can be different data type. Class is good for creating character profile, such as containing both Name (String) and age (Integer).

Enum, is a type of class that only contain constant. If class is a character profile, then, Enum is a lore book that contain things that need to be reference, unchanged, throughout the program. In this comic, Enum is used for items. Unless an upgrade system is involved, items should have the same property.

Me, personally, would simply put name strings in Enum, but actual coding is flexible to make it less of a nightmare to come back and fix, so, as The Dark Lord says, not ideal, but fine.

Not code, PU = Processing Unit, used interchangeably with brain. TDK specifically says that because it sounds like, "Poo".

Expanding and cleaning up on a conversion I had with @suntreehq in the comments of this post:

Ruby is fine, I'm just being dramatic. It's not nearly as incomprehensible as I find JavaScript, Perl, or Python. I think it makes some clumsy missteps, and it wouldn't be my first (or even fifth) choice if I were starting a new project, but insofar as I need to use it in my Software Engineering class I can adapt.

There are even things I like about it -- it's just that all of them are better implemented in the languages Ruby borrows them from. I don't want Lisp with Eiffel's semantics, I want Lisp with Lisp's semantics. I don't want Ada with Perl's type system, I want Ada with Ada's type system.

One of these missteps to me is how it (apparently) refuses to adopt popular convention when it comes to the names and purposes of its keywords.

Take yield. In every language I've ever used, yield has been used for one purpose: suspending the current execution frame and returning to something else. In POSIX C, this is done with pthread_yield(), which signals the thread implementation that the current thread isn't doing anything and something else should be scheduled instead. In languages with coroutines, like unstable Rust, the yield keyword is used to pause execution of the current coroutine and optionally return a value (e.g. yield 7; or yield foo.bar;), execution can then be resumed by calling x.resume(), where x is some coroutine. In languages with generators, like Python, the behavior is very similar.

In Ruby, this is backwards. It doesn't behave like a return, it behaves like a call. It's literally just syntax sugar for using the call method of blocks/procs/lambdas. We're not temporarily returning to another execution frame, we're entering a new one! Those are very similar actions, but they're not the same. Why not call it "run" or "enter" or "call" or something else less likely to confuse?

Another annoyance comes in the form of the throw and catch keywords. These are almost universally (in my experience) associated with exception handling, as popularized by Java. Not so in Ruby! For some unfathomable reason, throw is used to mean the same thing as Rust or C2Y's break-label -- i.e. to quickly get out of tightly nested control flow when no more work needs to be done. Ruby does have keywords that behave identically to e.g. Java or C++'s throw and catch, but they're called raise and rescue, respectively.

That's not to say raise and rescue aren't precedented (e.g. Eiffel and Python) but they're less common, and it doesn't change the fact that it's goofy to have both them and throw/catch with such similar but different purposes. It's just going to trip people up! Matsumoto could have picked any keywords he could have possibly wanted, and yet he picked the ones (in my opinion) most likely to confuse.

I have plenty more and deeper grievances with Ruby too (sigils, throws being able to unwind the call stack, object member variables being determined at runtime, OOP in general being IMO a clumsy paradigm, the confusing and non-orthogonal ways it handles object references and allocation, the attr_ pseudo-methods feeling hacky, initialization implying declaration, the existence of "instance_variable_get" totally undermining scope visibility, etc., etc.) but these are I think particularly glaring (if inconsequential).

Dynamically vs Statically-Typed Programming Languages

Hiya!🌍💻 I know I haven't done one of these posts in a while but now I came up with a new topic to talk about!

Today, we're going to dive into the world of programming languages and explore the differences between dynamically-typed and statically-typed ones. I actually got the idea from explaining the whole difference between languages such as C# and Java to Lua and Python! Also just wanted to talk about how various languages handle data types~! So, buckle up, and let's get started~! 🚀

The Main Difference

It all lies in how they handle data types:

In a dynamically-typed language, the type of a variable is determined at runtime, which means you don't have to specify the type explicitly when declaring a variable.

In a statically-typed language, the type of a variable is determined at compile-time, and you must declare the type explicitly when defining a variable.

Example Code

Not getting the picture of what I'm talking about? No worries, let's take a look at some code examples to illustrate the difference. I'll use my beloved Lua (a dynamically-typed language) and C# (a statically-typed language)~!

Lua

C#

In the Lua example, we can see that we don't need to specify the data type of the variable x. We can even change its type later in the code and it would still work!

In the C# example, we must specify the data type of x when declaring it, and attempting to change its type later will result in a compile-time error. Remember though, you can convert an int to string in C# via 'Convert.ToString()'!

Recap!

In dynamically-typed language, the type of a variable is determined at runtime.

Lua, Python, and JavaScript are programming languages that are dynamically typed.

In a statically-typed language, the type of a variable is determined at compile-time.

C#, Java, and Go are programming languages that are statically typed.

Obviously, there is more to know about each type as dynamically-typed and statically-typed languages each have their advantages and disadvantages - but I wanted to focus more on the data type declaration part~!

Here are some further reading pages:

That's all, thanks for reading, and hope you learned something new! Happy coding, folks~! 🌟💻🚀

What Is a Dynamically Typed Language?

When learning Python, you might hear the term “dynamically typed language” frequently. But what does it mean? Let’s break it down.

Typing refers to type-checking—the process of verifying whether the data types in your code are compatible with the operations being performed.

1️⃣ Strongly vs. Weakly Typed Languages

Strongly-Typed Languages (e.g., Python): These languages don’t allow type-coercion (implicit type conversion). For example:

pythonCopy code"1" + 2  # TypeError: cannot concatenate 'str' and 'int'

Weakly-Typed Languages (e.g., JavaScript): These languages allow type-coercion:

javascriptCopy code"1" + 2  // Outputs: "12"

2️⃣ Static vs. Dynamic Typing

Type-checking can occur at two stages:

Static Typing (e.g., Java, C++): Data types are checked before the program runs. You must declare the type of variables explicitly:

javaCopy codeintx=10; 

Dynamic Typing (e.g., Python): Data types are checked during program execution. Variable types are inferred automatically:

pythonCopy codex = 10  # No need to declare 'x' as an integer.

Python: A Dynamically Typed Language

Since Python is an interpreted language, it executes code line by line. Type-checking happens on the fly, allowing you to write flexible and concise code.

Example: pythonCopy codex = "Hello"x = 10  # No error—Python allows 'x' to change types.

This flexibility makes Python beginner-friendly but also increases the risk of runtime errors if types are misused.

Key Takeaway

Dynamic typing simplifies coding by removing the need for explicit type declarations. However, it also requires careful testing to ensure type-related bugs don’t creep in.

Python learners, embrace dynamic typing—it’s one of the reasons Python is so versatile and fun to use!

Understanding Java Data Types: A Comprehensive Guide

Java, one of the most widely used programming languages, is known for its portability, security, and rich set of features. At the core of Java programming are data types, which define the nature of data that can be stored and manipulated within a program. Understanding data types is crucial for effective programming, as they determine how data is stored, how much memory it occupies, and the operations that can be performed on that data.

What are Data Types?

In programming, data types specify the type of data that a variable can hold. They provide a way to classify data into different categories based on their characteristics and operations. Java categorizes data types into two main groups:

1. Primitive Data Types

2. Reference Data Types

Why Use Data Types?

1. Memory Management: Different data types require different amounts of memory. By choosing the appropriate data type, you can optimize memory usage, which is particularly important in resource-constrained environments.

2. Type Safety: Using data types helps catch errors at compile time, reducing runtime errors. Java is a statically typed language, meaning that type checks are performed during compilation.

3. Code Clarity: Specifying data types makes the code more readable and understandable. It allows other developers (or your future self) to quickly grasp the intended use of variables.

4. Performance Optimization: Certain data types can enhance performance, especially when dealing with large datasets or intensive calculations. For example, using int instead of long can speed up operations when the range of int is sufficient.

5. Defining Operations: Different data types support different operations. For example, you cannot perform mathematical operations on a String data type without converting it to a numeric type.

When and Where to Use Data Types?

1. Choosing Primitive Data Types:

Use int when you need a whole number without a decimal, such as counting items.

Use double for fractional numbers where precision is essential, like financial calculations.

Use char when you need to store a single character, such as a letter or symbol.

Use boolean when you need to represent true/false conditions, like in conditional statements.

2. Choosing Reference Data Types:

Use String for any textual data, such as names, messages, or file paths.

Use Arrays when you need to store multiple values of the same type, such as a list of scores or names.

Use Custom Classes to represent complex data structures that include multiple properties and behaviors. For example, a Car class can encapsulate attributes like model, year, and methods for actions like starting or stopping the car.

1. Primitive Data Types

Primitive data types are the most basic data types built into the Java language. They serve as the building blocks for data manipulation in Java. There are eight primitive data types:

Examples of Primitive Data Types

1. Byte Example

byte age = 25; System.out.println(“Age: ” + age);

2. Short Example

short temperature = -5; System.out.println(“Temperature: ” + temperature);

3. Int Example

int population = 1000000; System.out.println(“Population: ” + population);

4. Long Example

long distanceToMoon = 384400000L; // in meters System.out.println(“Distance to Moon: ” + distanceToMoon);

5. Float Example

float pi = 3.14f; System.out.println(“Value of Pi: ” + pi);

6. Double Example

double gravitationalConstant = 9.81; // m/s^2 System.out.println(“Gravitational Constant: ” + gravitationalConstant);

7. Char Example

char initial = ‘J’; System.out.println(“Initial: ” + initial);

8. Boolean Example

boolean isJavaFun = true; System.out.println(“Is Java Fun? ” + isJavaFun);

2. Reference Data Types

Reference data types, unlike primitive data types, refer to objects and are created using classes. Reference data types are not defined by a fixed size; they can store complex data structures such as arrays, strings, and user-defined classes. The most common reference data types include:

Strings: A sequence of characters.

Arrays: A collection of similar data types.

Classes: User-defined data types.

Examples of Reference Data Types

1. String Example

String greeting = “Hello, World!”; System.out.println(greeting);

2. Array Example

int[] numbers = {1, 2, 3, 4, 5}; System.out.println(“First Number: ” + numbers[0]);

3. Class Example

class Car {     String model;     int year;

    Car(String m, int y) {         model = m;         year = y;     } }

public class Main {     public static void main(String[] args) {         Car car1 = new Car(“Toyota”, 2020);         System.out.println(“Car Model: ” + car1.model + “, Year: ” + car1.year);     } }

Type Conversion

In Java, type conversion refers to converting a variable from one data type to another. This can happen in two ways:

1. Widening Conversion: Automatically converting a smaller data type to a larger data type (e.g., int to long). This is done implicitly by the Java compiler.

int num = 100; long longNum = num; // Widening conversion

2. Narrowing Conversion: Manually converting a larger data type to a smaller data type (e.g., double to int). This requires explicit casting.

double decimalNum = 9.99; int intNum = (int) decimalNum; // Narrowing conversion

Conclusion

Understanding data types in Java is fundamental for effective programming. It not only helps in managing memory but also enables programmers to manipulate data efficiently. Java’s robust type system, consisting of both primitive and reference data types, provides flexibility and efficiency in application development. By carefully selecting data types, developers can optimize performance, ensure type safety, and maintain code clarity.

By mastering data types, you’ll greatly enhance your ability to write efficient, reliable, and maintainable Java programs, setting a strong foundation for your journey as a Java developer.

A curious cultural phenomenon that actually exists: the term Indo or a short version of ‘Indo-European’ traditionally meant, in Indonesia or former Dutch East Indies, as ‘people of European descent (predominantly Dutch but can be everything really) who are connected to Dutch East Indies (colonial Indonesia) and are oftentimes mixed with native Indonesians but also include pure Dutch (totok)’. These days this also includes anyone who’s of mixed White and Indonesian heritage even though they’re obviously not connected to colonial Indonesia, because y’know, Indonesia became independent in 1945 but obviously we still had contact with the Western world afterwards. Another term we use to refer to mixed White-Indonesians is blasteran which is a mix of ‘blaster’, a word loaned from Dutch ‘bastaard’ + Indonesian suffix ‘an’ which is like… making a noun out of the thing it’s affixed with.

When I was a child, the term Indo was used interchangeably with blasteran. However, these days, or a good two decades afterwards — something has changed. In the era of internet and social media, Indonesians start to refer to themselves as ‘Indo’, supposedly to abbreviate Indonesia because it’s too long to type (something we do a lot with basically everything). So you have two usages of Indo in the country! But for some reason, less and less people use the word ‘Indo’ to refer to people of mixed descents while the word blasteran persists more (to my own observation). This definitely also happens to me — when I see mixed people I call them blasteran, while ‘Indo’ is just a word I use to refer to, well, myself who is full native.

There is a definite cultural shift. Also, I have to point out that the word blasteran has no exact connotation with colonial era, something the word Indo has. Besides, unlike during the time of my childhood, less and less original ‘Indos’ are visible because they’re becoming more and more native Indonesian with each passing moment, or at least that’s what the public eye thinks and feels. We do have less original Indo community compared to the Netherlands (a topic for another post if I make any about this matter) and Indonesia has about 280 million population, which means the full-blooded natives highly outnumber any mixed communities. Therefore, for better and worse — out with the old ‘Indo’, in with the new ‘Indo’.

This is apparently predicted by Sutan Sjahrir, one of our founding fathers, and I had goosebumps when I read this because, damn, dude is RIGHT.

EDIT: THIS IS BASED ON MY PERSONAL EXPERIENCE because after I discussed it with frens, their experiences with the word ‘Indo’ in a cultural sense (including family customs etc) are highly variable. For context, I am Javanese and my family used to be fluent in Dutch and we still used some Dutch words and terms especially when I was a kid. Other people especially outside Java could have different experiences with the usage of this word.

Exerpts from my absolute onslaught of “clarifying” comments on my “simple” calculator assignmeng for AP compsci principles (it is over 182 lines long)

(we’re starting our python unit. I already know basically everything that will be taught in this unit. wtf (teacher said ill get to code fish game as a project if i want /pos))

#unrelated but have you seen that one code of a like, C# or java coded calculator that can add/subtract/divide/multiply any two individual numbers up to 60-something and the coder did it by coding something else to hard code every operation. like, if num1=3 and num2=5 and operation=addition answer=8 type of thing? terrifying. I want to do it. (i looked for the code but couldn't find it (sad))

#I need blank lines and I can't be bothered to check if /n works in python. Also this is funnier [in relation to me using 'print("")' to get blank lines on the terminal]

#(extra or statements to account for user error (i don't want to figure out how to ignore whether a letter is caps or lowercase so i will instead code more. This is my mantra.))

#(you know it's sad that python doesn't use semicolons to seperate commands because in languages that do use it I can just code EVERYTHING on one line and the camp counselors didn't like that but they couldn't do anything because it was technically correct lol)

[computerlanguages]

Computer Language

Computer languages, also known as programming languages, are formal languages used to communicate instructions to a computer. These instructions are written in a syntax that computers can understand and execute. There are numerous programming languages, each with its own syntax, semantics, and purpose. Here are some of the main types of programming languages:

1.Low-Level Languages:

Machine Language: This is the lowest level of programming language, consisting of binary code (0s and 1s) that directly corresponds to instructions executed by the computer's hardware. It is specific to the computer's architecture.

Assembly Language: Assembly language uses mnemonic codes to represent machine instructions. It is a human-readable form of machine language and closely tied to the computer's hardware architecture

2.High-Level Languages:

Procedural Languages: Procedural languages, such as C, Pascal, and BASIC, focus on defining sequences of steps or procedures to perform tasks. They use constructs like loops, conditionals, and subroutines.

Object-Oriented Languages: Object-oriented languages, like Java, C++, and Python, organize code around objects, which are instances of classes containing data and methods. They emphasize concepts like encapsulation, inheritance, and polymorphism.

Functional Languages: Functional languages, such as Haskell, Lisp, and Erlang, treat computation as the evaluation of mathematical functions. They emphasize immutable data and higher-order functions.

Scripting Languages: Scripting languages, like JavaScript, PHP, and Ruby, are designed for automating tasks, building web applications, and gluing together different software components. They typically have dynamic typing and are interpreted rather than compiled.

Domain-Specific Languages (DSLs): DSLs are specialized languages tailored to a specific domain or problem space. Examples include SQL for database querying, HTML/CSS for web development, and MATLAB for numerical computation.

3.Other Types:

Markup Languages: Markup languages, such as HTML, XML, and Markdown, are used to annotate text with formatting instructions. They are not programming languages in the traditional sense but are essential for structuring and presenting data.

Query Languages: Query languages, like SQL (Structured Query Language), are used to interact with databases by retrieving, manipulating, and managing data.

Constraint Programming Languages: Constraint programming languages, such as Prolog, focus on specifying constraints and relationships among variables to solve combinatorial optimization problems.

[the-starlight-papers]

I am being aggressively reminded on why I don’t work on projects late at night and that is because last night I was loosing my goddamn mind because I learned that python doesn’t require you to declare variable types.

What do you MEAN I can just do n=4 in one line and then n=“cat” the next line???? My AP CSA Java brain DOES NOT like that.

I haven’t done python in like 3 years and I’m only frantically relearning it because I got an adafruit trinket board to run some LED. You can theoretically use it with the Arduino IDE and program it with C++. Which would be REALLY NICE because that’s where I have completed code written. But despite my best efforts it refuses to get programmed. So now I get to rewrite all my code in python.

Good times good times.

At least now I can include different blade modes on the same file and just only uncomment one so that my sister can swap between modes easier.

Coding Language Tag Game!

Rules: Talk about your most favourite and least favourite coding language, and tag more codeblrs to do the same!

Tagged by: @kitkatcodes (Thanks for the tag!)

I tag: @alica-tech and whoever wants to do this tag

My favourite language is probably Java (gasp). It was the second programming language I learned at school (after Python), and the language we used in classes since then. Apparently the guy who created the language went to my university during his bachelor degree, so we think that's why all of our profs are so eager to have us learn it. I know not everyone likes it, but I do. I really like how rigid it is, since it forces me to actually know what's going on. I love how I have to declare what data types my variables are; there's no guessing involved now. My one problem with Java though is the syntax for certain stuff. You mean to tell me I have to know the difference between length, length(), and size()? I gotta sit down and actually try to learn when to use what.

I don't think I have a least favourite language...? I did a bit of C/C++, but only a few lines of code. Getting C++ all set up was a pain. But speaking of languages that are a pain to set up; R. Oh god, it took me days to get R to run on my laptop for my thesis project. Mostly because the libraries I was using wasn't compatible with certain versions of R (versions of R that were compatible with an M1 Apple laptop), and so spending literal days trying to get everything to work with R was a nightmare. The language itself is fine; I really like how I can highlight the specific block of code I want to run instead of the whole program. But the setup...if that counts, then R is my least favourite language.

I feel like that meme of like "person who's only seen Les Mis and Aladdin watching a 3rd movie - when does he steal the bread?"

I'm watching a Java programming tutorial, with most of my programming experience coming from the Matlab class I took in college. And one of my first thoughts in the video going over basic types of variables and stuff was "so, where do the matrices come in?"

(it's not until video 16)
